 * @property {Object[]} orderBy
 *   The order to apply to the query results.
 *
 *   Firestore guarantees a stable ordering through the following rules:
 *
 *    * Any field required to appear in `order_by`, that is not already
 *      specified in `order_by`, is appended to the order in field name order
 *      by default.
 *    * If an order on `__name__` is not specified, it is appended by default.
 *
 *   Fields are appended with the same sort direction as the last order
 *   specified, or 'ASCENDING' if no order was specified. For example:
 *
 *    * `SELECT * FROM Foo ORDER BY A` becomes
 *      `SELECT * FROM Foo ORDER BY A, __name__`
 *    * `SELECT * FROM Foo ORDER BY A DESC` becomes
 *      `SELECT * FROM Foo ORDER BY A DESC, __name__ DESC`
 *    * `SELECT * FROM Foo WHERE A > 1` becomes
 *      `SELECT * FROM Foo WHERE A > 1 ORDER BY A, __name__`
 *
 *   This object should have the same structure as [Order]{@link
 * google.firestore.v1beta1.Order}
 *

 *   A starting point for the query results.
 *
 *   This object should have the same structure as [Cursor]{@link

 *
 * @property {Object} endAt
 *   A end point for the query results.
 *
 *   This object should have the same structure as [Cursor]{@link

 *
 * @property {number} offset
 *   The number of results to skip.
 *
 *   Applies before limit, but after all other constraints. Must be >= 0 if
 *   specified.
 *
 * @property {Object} limit
 *   The maximum number of results to return.
